A computer-implemented method of predicting rock properties of a subsurface formation using reflection seismic data and well log data. Synthetic seismic data is generated from the well log data and quantized into discrete synthetic data subcells based on rock property-predictive seismic attributes of the synthetic seismic data. The reflection seismic data is also quantized into discrete reflection data subcells based on the same seismic attributes used to quantize the synthetic seismic data. Each reflection data subcell is correlated with a corresponding synthetic data subcell based on the seismic attributes of the reflection and synthetic seismic data. A statistical distribution of well log properties associated with the synthetic seismic data subcells is then assigned to corresponding reflection data subcells, which can be viewed as 2D seismic lines, 3D seismic volumes, or single data point histograms.
